What causes pain when lifting or was back training yesterday?

In recent years, the correct lifting technique in connection with back pain has been increasingly questioned. The biomechanical loads are often not very different for different lifting techniques, and people with back pain often show more protective behavior and even tend to move their back less.again, there is increasing evidence that pain during lifting, a very mechanical-seeming problem, is influenced by various non-mechanical factors.In this observational study, Saraceni and colleagues investigated this in more detail and compared a group with and a group without back pain during a lifting task.All participants had a manual job and had to lift at least 20 objects per day.Various psychological, work- and lifestyle-related, general health and psychophysical factors were collected and examined to see whether there were differences between the groups.There were no differences between the people with regard to the psychological factors. However, it was striking that the group with back pain reported subjectively poorer sleep quality and had more general symptoms such as more pain in the body, digestive problems and pseudo-neurological symptoms.It is important to point out that this was only a snapshot with a small study population and therefore no causality can be inferred.Nevertheless, this is another piece of the puzzle that points in the direction that persistent pain is more likely to be due to dysregulation of the neuroimmunological, endocrinological system.What is your experience in the clinic?
